This list contains all existing texture properties. If you implement a Graphic, Audio or Physics module you have to stick to this list. You are not required to support all texture properties mentioned here but if you support them stick to the definition below. Artist rely on the same list to produce their content. For testing new texture properties you can define new properties and propose them for inclusion.
Property names typically compose of one or more names with optional dots in between. Color components and gray scale values are written in the range from 0 to 1 with 0 equal to an RGB value of 0 and 1 equal to an RGB value of 255. Values with more than one color component are written in paranthesis. You are not required to use the full number of components written. Using less is valid and the modules fill up the remaining components with their default values.
Some texture properties have boolean values. The Drag[en]gine does though not use a boolean data type only float data types. As a rule of thumb values below 0.5 are treated as 0 (or false) and all other values a 1 (or true). To avoid troubles though it is best to stick to 0 and 1 as values in these cases.
The properties are listed in a summary table sorted alphabethically by name. Click on a name to find details about the texture property in question.
